Abstract
En 中文
In this study, synergistic regulation of PAN/Fe3O4 composite nanofibers was achieved through thermal-magnetic-compositional coupling. By leveraging the magnetic focusing effect mediated by an electromagnetic lens combined with temperature regulation, the jet stability, fiber structure, and magneto-mechanical properties were optimized. Under the optimal conditions of 50 ℃ and 1 A magnetic field, the fiber diameter was reduced to 266.44 nm (25.1% lower than that of the non-magnetic control group), and the tensile strength reached 1595.276 kPa (21.7% higher than that of the non-magnetic group at 30 ℃). The maximum film thickness reached 0.950 mm (48% increase compared with the non-magnetic group), while the deposition area shrank from 93.46 cm² to 73.09 cm² at 30 ℃; the porosity decreased from 42.8% of the non-magnetic control group to an optimal 22.2% (a 48.1% reduction), and the magnetic properties were generally improved. The optimal coupling window realized the synchronous optimization of fiber structure and magneto-mechanical properties, providing a distinct strategy for the customization of nanofibers.
